witha Cbarp Knife, and ufing a Microfcope I fcver'd before ray 
eyes the mcmbran from it ; whereby I plainly faw that fine 
membranor film, in which ihefe Carneous fibres lie interwoven, 
and of which I fpeak in the above- mention'd Letter of the firfl 
June 1674 where I fay^that thofe Merobrans are made up of 
To many filaments or thredsj as if without naked Eye we faw 
the omentum of an Animal. Gbferving there Membrans more 
narrowly, I faw, that they do wholly and only confift of fmall 
threds ranoing through one another; of which fome, to my 
eye, apptar d to be 10, 20, and fome 50 times thinner thana 
hair. 
Having taken off the faid Membrans from the faid Carneous 
filaments, I faw very clearly thefe Carneous threds, which in this 
piece of fltfli were as thick as a hair on ones hand. Where they 
Jay fomewhat thick upon one another, they appeared red* but 
the thinner they werefpread, the clearer they (hew'd. 
I have ured feveral methods of obferving,to fee the panicles 
of thefe Carneous filaments, and have always found, tl^at they 
are compofed of fuch parts, to which I can give no other fi- 
gure than globular* Moreover, I have divided before my Eye 
inromany fmall parts very fmall pieces of thefe Carneous fila- 
ments, which pieces were feveral times fmaller than a grain of 
Sand ; and I have obferved befides, that, when the flefb is frcfli 
and moift, and the globuls thereof are preflTed or rubbed , they 
dilTolve and run together, as if you faw an oily or thick waterifli 
matter. 
Thefe globuls > of which I fay that the Carneous filaments 
do confift, are fo fmall, that, if I may judge by my fight, I muft 
needs (ay,that ten hundred thoufand of them would not make one 
grain of gravel-Sand. 
And having formerly written to you^tbat the particles,which 
do conftitutefle(b,fat,bones,hair, &c. (which I call globuls) are 
not perfeft globuls, but only come near fuch ; I fliall now re- 
peat fomething of that maiter; Idefire you to confider only, 
that a great number of Sheeps bladders , fiird with water, and 
held in the Air , and every where furroundedby the fame, are 
round, but if you throw them together into a Tun, they will 
lofe their roundefs,and fall clofe together,wbereby each bladder 
will come to have its peculiar figure, they being very flexible 5
